Follow-up to MDEV-16328: ALTER TABLE…page_compression_level should not rebuild table

Browse Source 
Allow combination of non-instant, non-rebuilding operations with
changes of table options that do not require a rebuild.

For example, DROP INDEX or ADD INDEX can be performed with
ALGORITHM=NOCOPY together with changing such table options.
Changing the table options alone would be allowed with ALGORITHM=INSTANT.

INNOBASE_ALTER_NOCREATE: A new set of flags, for operations that
are refused for ALGORITHM=INSTANT and do not involve creating
index trees.

Move ALTER_RENAME_INDEX to the proper place (INNOBASE_ALTER_INSTANT).

innobase_need_rebuild(): Do not require a rebuild if
INNOBASE_ALTER_NOREBUILD operations are combined with ALTER_OPTIONS.

ha_innobase::prepare_inplace_alter_table(),
ha_innobase::inplace_alter_table(): Use the fast path if
ALTER_OPTIONS is combined with INNOBASE_ALTER_NOCREATE.
In this case, the actual changes would be deferred to
ha_innobase::commit_inplace_alter_table().
